Okay basically im having alot of rattling issues in the car for the past 2 weeks,I've had a loud clunk in my passenger side rear end everytime i go over potholes,ridges or anything on the road that should make the suspension move alot and it happens only on the passenger side towards the rear it almost sounds like tennis balls that come in plastic tubes and u shake it up and down(just to give u a visual of what im talking about). but lately it seems everything in my car rattles now the whole dash,door panels chirps and or rattles when front suspension hits even the smallest bump B-pillars seems to make noises I've taken the plastic covers off(Both b-pillar) and foamed everything and its quieted down a bit but is still making noises and i've noticed alot of rattling towards the rear of the car, sounds as if its hollow and every little thing echoes in there. what can i do? BTW I've been to the dealership twice and they tell me they dont know what it is they cant find where its coming from. Is this an acceptable answer? or should i really look into fighting this?
